-----
Usage:

This changes the behavior pattern determination process for Enemies tagged in the Note field.

Note field Tag (Enemies):

<actionPrepare:50>
When an action cannot be performed due to reasons such as insufficient MP when performing multiple actions or applying silence before using a spell, this will re-roll the action.
The value set in the tag is the probability of re-rolling; for example, 50 means a 50% chance of re-rolling.

使い方:

  メモ欄にタグを付けた敵キャラの行動パターン決定処理が変化します。


メモ欄タグ（敵キャラ）:

  <actionPrepare:50>
    複数回行動時のＭＰ不足、魔法使用前に沈黙付加、などの理由で行動が実行
    できなくなったときに、行動の再抽選を実行します。
    タグに設定した数値が再抽選の実行確率となります、50 なら５０％で再抽選。
